Counselors (N = 911) reported the research skills needed for practice and subsequent research training needs. Findings indicate that counselors have a high need for research skills at work, but training needs differ significantly by counselor type. Recommendations include increasing emphasis on single‐case design, survey design, and widely available data analysis tools. 相似文献

All universities in Australia are asked to develop various attributes in their degrees. From 2011, the Australian Qualifications Framework has stipulated some of these attributes for the various levels of qualifications. There are many challenges that face assuring the development of graduate attributes in a Bachelor of Arts as the degree typically has very few core units (if any), a wide choice of subjects, a limited prerequisite structure and, unlike many professional degrees, the BA does not have an external accrediting body. This paper describes an approach used to identify the pathway undertaken by each individual student in a History major of the Bachelor of Arts. This pathway was used to identify the graduate attributes that each student should have developed, as articulated by the lecturers. Student perceptions were then compared with the graduate attributes that were intended to be developed through each individual's combination of units studied. In summary, through analysing the two methods (student perceptions and unit pathway) we found that they concurred with respect to only three-quarters of the graduate attributes. Possible reasons for the discrepancies and future research are discussed. The need for multiple methods of providing evidence of the development of graduate attributes is confirmed. 相似文献

Through a qualitative interview design, this study investigated how participation in a rigorous academic environment may influence gifted students who demonstrate high levels of perfectionism. The study also examined how their responses to a rigorous academic and residential environment may differ according to the type of perfectionism. Findings indicated that some socially prescribed perfectionists reported an increase in perfectionism, whereas some self-oriented perfectionists reported an increase followed by a decrease in their perfectionism. Overall, the majority of the participants, regardless of their type of perfectionism, indicated a decrease in their perfectionism as a result of their new academic environment. Reactions to experiencing imperfections ranged from calm to guilt or even anger, depending on the type of perfectionism. Implications for working with gifted students who show high levels of perfectionism are discussed. 相似文献

This study is part of a larger research project at the Image Permanence Institute dedicated to digital print preservation issues – the Digital Print Preservation Portal (DP3). Previous DP3 studies determined that certain digital print types are prone to cracking and/or abrasion, and that factors such as low relative humidity, pollutants, and light increase the brittleness of the ink-receiving layer of some inkjet papers. The purpose of this investigation was to explore if light also increases the propensity of inkjet prints to abrade, and to examine the potential of framing glazings to mitigate light-induced physical damage (cracking and abrasion) by attenuating some portion of the UV spectrum. Inkjet papers and prints were subjected to xenon lighting (to simulate daylight through window glass) without glazing, or in sealed framing packages with plain framing glass (soda-lime) or UV filtering glass. Before and after light exposure, brittleness, and abrasion resistance were evaluated independently using two tests: ISO 18907 (Imaging materials – Photographic films and papers – Wedge test for brittleness) and a rub test utilizing a Sutherland® Rub Tester. In this study, exposure to light increased the cracking and/or abrasion tendency of some specimens. The use of UV filtering glass reduced this light-induced propensity in all cases. Plain glass protected all samples from at least one of these two types of surface damage, but was less effective than UV glass. Light-induced brittleness and sensitivity to abrasion were mostly, though not exclusively, caused by UV radiation. It was also seen that some prints may become brittle and/or prone to abrasion in the absence of image fade. Budgeting the amount of light these objects can be exposed to, protecting them from UV radiation, and handling prints with caution especially after exhibition, is essential in order to limit physical damage. 相似文献
